TO ALL WHDM IT MAY oonosem.

Be it known that I, S. D. McPHEuSON, of Normal, in the county of McLean,ahd in the State of Illinois,

have invented certain new/and useful Improvements in Compound for MakingPictures Transparent; and do hereby declare that the following is afull, clear, and exact description of the mode of compounding and usingthe same. I

To prepare a smallquantity of this compound, I use, first, b'alsam* fir,two ounces; second, Demar varnish,

one ounce; third, alcohol, half an ounce; fourth, turpentine, one ounce.

These ingredients, in the above proportions, are placed in a. bottle,and well shaken. After they have become thoroughly united,.which will bethe case in a. few moments, the compound is applied to the pictur withan ordinary varnish-brush.

The pictureis placed with its face downward and upon glass, or someequivalent substance. The compound is then put on the back of thepicture, and renders it so transparent that the back can be readilypainted inoil colors, thus giving the appearanc, of an oil-coloredpainting to the face.

What I claim, is- The within-described ingredients, compounded and usedsubstantially as and for the purpose set forth. In testimony thatI'claim thefor'egoi ng, I'have hereunto set my hand, this 19th day ofOctober, 1.867.
